I have noticed a couple of reddish spots on the tip of my penis. They aren t blistery or scabbed. I don t feel any discomfort when urinating. The spots feel a little tender when touched, but not painful. Girlfriend doesn t have herpes, nor have I ever had. Could this be a symptom of my penis rubbing against the toilet seat after being cleaned with a bleach type cleanser and not rinsed off properly? I noticed a couple of dark spots when I was first made aware and then a couple of days later I noticed they had turned into two spots looking like burns. Any thoughts?
